A continuous one$-$way floor slab spans between beams spaced with a regular $4\mathrm{.}5-m$ clear span

$($the web widths of the integral supporting beams are $300-mm$ wide$).$ The specified floor

loading consists of a live load of $4\mathrm{.}8$kPa and a superimposed dead load of $2\mathrm{.}4$kPa, in addition

to self$-$weight. Design the slab thickness and longitudinal reinforcement at the support and

midspan regions, consistent with all strength and detailing requirements.

Assume $f_c=30$MPa and $f_y=400$MPa, interior exposure conditions, and that the slab

comprises more than $2$ spans. Note that your designs should have a common slab thickness for

both $($i$.$e$.,$ negative and positive$)$ regions and should be designed considering the worst$-$case

negative and positive bending moments that must be considered for the continuous slab.
